Yaqui Gulch Road (Mariposa County)

 

Yaqui Gulch Road is an approximately 3-mile rural highway located in Mariposa County.   This highway corridor is one of the oldest identifiable roadways in the state as it once served the original Mariposa County seat of Aqua Fria along with nearby Guadalupe and Bridgeport.  The community of Agua Fria was founded in 1849 by Sonoran Miners and became the first Mariposa County seat in February 1850.  The County Seat was not long lived in Agua Fria as it would be moved to Mariposa in November 1851.  The community of Agua Fria would burn during a fire in 1866 and was never rebuilt.  




Part 1; the history of Yaqui Gulch Road

Yaqui Gulch Road was once consolidated with what is now Aqua Fria Road.  Both Aqua Fria Road and Yaqui Gulch Road connected the early Mariposa County communities of Agua Fria, Guadalupe and Bridgeport.  

Mariposa County was incorporated on February 18, 1850, as one of the original counties following California becoming an American state.  Mariposa County initially was by far the largest county by area in California which was centered around mining claims in the Sierra Nevada foothills.  The original county seat was the now ghost town of Aqua Fria.

Aqua Fria was centered around claims struck by Sonoran miners in 1849.  The town site was located near Agua Fria Creek near two cold water springs.  At the height of the community, it boasted about a dozen stores, several gambling halls and a hotel.  The Aqua Fria Post Office would open on October 7, 1851.  Despite Agua Fria obtaining Post Office service the Mariposa County seat would relocate to Mariposa on November 10, 1851.

Guadalupe was located approximately two miles south of Agua Fria near the confluence of Guadalupe Creek and Aqua Fira Creek.  This mining community would emerge in the early 1850s but was never very large in size.  By 1859 a 15-stamp mill would operate at Guadalupe.  

Bridgeport was founded in 1852 at the highway crossing near Aqua Fria Creek which was on the Fremont Land Grant site.  The community reached a peak population of about 3,000 during the California Gold Rush and was once the home of the Washburn Brothers who would later construct the Wawona Road (now in Yosemite National Park).   

After losing the Mariposa County seat the community of Aqua Fria began a quick decline.  The community would be destroyed during a fire on June 22, 1866, and would never be rebuilt.  Despite being then recently destroyed the community of Agua Fria appears on the 1868 Whitney map of the Sierra Nevada adjacent to Yosemite Valley.  What is now Agua Fria Road (Upper and Lower) appears on the map connecting Princeton (now Mount Bullion) to the now ghost town Guadalupe.  Bridgeport can be seen a short distance south of Guadalupe on Agua Fria Creek and along an unmarked connecting road to White Rock.  Bridgeport would finally fade in the twentieth century when the modern alignment now used by California State Route 140 was constructed to the north what is Old Highway (the original alignment of the Yosemite All-Year Highway.




Part 2; a drive on Yaqui Gulch Road

Northbound Yaqui Gulch Road begins at the intersection of Old Highway and Buckeye Road.  The community of Bridgeport would have been located a short distance to the west on Old Highway.  


Yaqui Gulch Road passes through Guadalupe Valley where the ghost town of Guadalupe was once located.





Yaqui Gulch Road passes through the namesake gulch and terminates at California State Route 140. 







The town site of Agua Fria is located a short distance of Yaqui Gulch Road via a short westward jog to the beginning of Agua Fria Road.  There is nothing to identify the site of Agua Fria now aside from historical plaques.

Petroleum Club Road (former California State Route 33 and US Route 399 past the Lakeview Gusher)

Petroleum Club Road is an approximately 5.3-mile rural highway located in the Sunset Oil Field of western Kern County.  This corridor was constructed as a frontage road of the Sunset Railroad and would be the site of the Lakeview Gusher in 1910.  Petroleum Club Road was the original alignment of California State Route 33 and US Route 399 between 1934-1938.  In 1938 the West Side Highway was constructed west of Lakeview Gusher and still serves as the current alignment of California State Route 33.   Part 1; the history of Petroleum Club Road Petroleum Club Road is the original highway which linked the oil communities of Maricopa and Taft.  Both cities were developed around the early boom of the Sunset Oil Field.  The early Sunset Oil Field can be seen centered along Cienega Canyon Road southwest of Buena Vista Lake in Township 11 North, Range 23 West on the 1898 Kern County Surveyors map .  In 1901 Post Office Service would be established at the Su...

Hawaii Route 50

Hawaii Route 50 is the longest Sign Route on the island of Kauai at 32.6 miles.  The entirety of Hawaii Route 50 is overlaid atop Kaumualii Highway from Lihue west to the Pacific Missile Range Facility at Barking Sands. Hawaii Route 50 is one of the original 1955-era State Highway designations on Kauai.  Much of the Kaumualii Highway corridor was constructed during the sugar plantation boom of the late Hawaiian Kingdom.  The first tee beam bridge in Hawaii would be constructed along the Kaumualii Highway in 1911 at the Hanapepe.  Much of this highway would be modernized to two-lane standards through the 1930s and 1940s.

Did Caltrans just kill the G26 cutout US Route shields?

The US Route System was formally created by the American Association of State Highway Officials during November 1926.  Through the history of the system the only state to which has elected to maintain cutout US Route shields has been California.  The G26 series cutout US Route shields have become a favorite in the road enthusiast hobby and are generally considered to be much more visually pleasing than the standard Federal Highway Administration variant.  However, the G26 shield series appears to have been killed off on January 18, 2026, when Caltrans updated their Manual of Uniform Traffic Control Devices.  This blog will examine the history of the US Route shield specifications in California and what is happening with the 2026 changes.  The blog cover photo is facing towards the terminus of California State Route 136 and at a G26-2 specification US Route 395 shield.  In the background Mount Whitney can be seen in the Sierra Nevada range.   ...
